Frequently Asked Questions
Common questions about NEMA NEMA 11-50P cords and connectors
The NEMA 11-50P is a NEMA connector rated 50 A at 250 V, 3-pole, 3-wire (ungrounded, legacy), for single-phase circuits. It uses the standard NEMA non-locking straight-blade configuration. The trailing P identifies it as a male plug; it pairs only with the matching NEMA 11-50R.
The 50 A 250 V NEMA 11-50P is typically used for older 250 V industrial and commercial equipment and some welders without a separate equipment ground. Selecting the correct 50 A 250 V connector ensures the contacts and cable can carry the load without overheating and that the single-phase supply is connected with the proper grounding and polarity.
The NEMA 11-50P is the male plug, typically fitted on the end of a power cord or equipment inlet lead, and it only mates with a matching NEMA 11-50R female receptacle (socket-outlet or cord connector). It carries 50 A at 250 V in a 3-pole, 3-wire (ungrounded, legacy) configuration, so the outlet, wiring and overcurrent protection must all be rated for at least 50 A.
No. NEMA connectors are keyed by voltage, current, phase and grounding, so the NEMA 11-50P mates only within its own 50 A 250 V family. The ungrounded 11-series is a legacy configuration; it cannot mate with grounded 6-series connectors, and modern replacements should add proper equipment grounding. When two configurations must be joined, use a properly rated, UL-listed adapter or cord set, and never exceed the lowest current rating in the chain.
Yes. We manufacture UL/cUL and ETL listed NEMA 11-50P cord sets, rewireable plugs and receptacles, and molded connectors using RoHS, REACH, PAHS and Proposition 65 compliant cable, with custom lengths, wire gauges, jacket colors, strain relief and labeling. MOQ is typically 200-1000 pieces, samples ship in 7-15 days and bulk production takes 15-20 working days.
